aquaculture are typically thousand fold greater than wild environments. Modern fish culturists employ both open and close systems to raise fish. Open systems‚ such as‚ the raceways are characterized by rapid turnover of water. Closed systems are commonplace in pond culture. Closed aquaculture systems do not have rapid turnover of water‚ but do not have a high surface to volume ratio facilitating exchange of gases‚ nutrients‚ energy etc. with the surroundings.

stop. The deforestation of our rainforests is effecting our environment and us more than you may think. We get the oxygen we need from trees‚ forests protect us from Carbon Dioxide‚ and forests protect most of Earth’s plants and animals. We need trees to breathe and rainforests to protect us from harsh things that we emit from our bodies. Many rainforests help and protect us. “More than 20% of the world’s oxygen comes from the Amazon” (Fraser 2)‚ the Amazon is an immense rainforest located in South

------------------------------------------------- Anechoic chamber An anechoic chamber (an-echoic meaning non-echoing or echo-free) is a room designed to stop reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise. The combination of both aspects means they simulate a quiet open-space of infinite dimension‚ which is useful when exterior influences would otherwise give false results. Anechoic chambers were originally used in the context of acoustics (sound waves)

Carbon Dioxide is a colorless‚ odorless gas that occurs in small quantities in the earth’s atmosphere naturally. The earth’s ocean‚ soil‚ plants and animals release CO2. The formula of Carbon Dioxide is CO2. The CO2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon - oxygen double bonds. The atoms are arranged as so (OHT). This is called a ’linear molecule’. Carbon dioxide is commonly found as a gas and is never a liquid. It sublimes to
